Copies the specified object as a part of a multipart upload.
int CopyPart(const QString& qsSrcObjectName, const QString& qsDestBucket, const QString& qsDestObjectName, int iDestPartNumber, const QString& qsDestUploadId);
This method copies data from the object specified by SrcObjectName (in the bucket currently selected by Bucket) to a new multipart upload part for DestObjectName in DestBucket.
The DestPartNumber and DestUploadId parameters should be used in the same manner as the UploadPart method's PartNumber and UploadId parameters.
To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.
Note: This method is not supported when ServiceProvider is spGoogleStorage (2); Google Cloud Storage does not support multipart uploads.
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
